I have just bought a very nice front mounted petrol tank for my Ulster Special build.
The outlet is 1/8 BSP. I understand most are 1/4 BSP. I wondered whether the smaller diameter of the inner diameter could limit the fuel flow?
It appears to be slightly smaller than the end of the standard solder nipple that goes with 1/4 BSP.
Am I worrying unnecessarily?

It's way bigger than the 90 jet hole in your SU carb. I wouldn't worry

Mine's like that and it is not a problem!

Thanks, very good point, I feel a bit daft for asking now.
